Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically a locking mechanism for automotive high-voltage connectors. Background Technology

[0002] Currently, in the field of high-voltage connectors for electric vehicles, high-current connectors with large insertion and extraction forces require the design of a rotating arm to assist in docking. After docking, the limiting and fixing of the rotating arm directly affects the quality of the circuit connection. Existing locking mechanisms are unreliable and prone to loosening. A search revealed existing technology with announcement number CN109546445B, whose working principle is as follows: a hook-shaped protrusion is provided on the upper front end of the plug housing body to engage with the hook-shaped body of the switch for locking; positioning shafts are provided on the left and right sides of the lower end of the plug housing body to match the positioning shaft holes; the plug housing and the rotating arm are rotatably connected through the engagement of the positioning shafts and positioning shaft holes. Although this can achieve locking after the plug and socket are connected, the switch needs to move on the rotating arm, thus requiring at least a mounting area for the switch on the rotating arm. Furthermore, the switch itself has a very complex structure, resulting in complex manufacturing of the locking structure for the plug and socket. Unlocking and locking require manual pushing of the switch, which affects the rapid locking of the plug and socket. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a locking mechanism for a vehicle high-voltage connector, comprising a socket and a plug; the outer side of the plug is rotatably connected to a rotating arm, and the rotating arm is also provided with a latch; both sides of the socket are provided with connecting pins, and after the rotating arm is inserted into the connecting pin through a provided slot, the connecting pin slides in a guide groove provided on the rotating arm; after the connecting pin enters the limiting hole provided on the guide groove, the latch is adapted to and connected with a locking pin provided on the outer wall of the plug to lock the plug onto the socket.

[0005] As a preferred technical solution of this utility model: the plug has a plug portion inside, and the socket is also provided with a plug slot for accommodating the plug portion.

[0006] As a preferred technical solution of this utility model: the inner wall surface of the socket is provided with a sliding groove, and the plug can be smoothly inserted into the socket by sliding along the guide rail provided on the socket through the sliding groove.

[0007] As a preferred technical solution of this utility model: the bottom of the plug is provided with a connecting part, and is connected to the connecting part by a wire clamp, so as to fix the power cord inside the plug.

[0008] As a preferred technical solution of this utility model: a sealing gasket is provided between the wire clamp and the connecting part, and the sealing gasket is sleeved outside the power cord.

[0009] As a preferred technical solution of this utility model: both sides of the wire clamp are provided with buckle grooves, which are connected to the buckle pins provided on the connecting part to fix the sealing gasket between the connecting part and the wire clamp.

[0010] The beneficial effects of this utility model using the above technical solution are as follows: Since a latch is directly provided on the rotating arm, the latch automatically engages with the locking pin after the plug and socket are connected when the rotating arm is rotated. Therefore, the locking mechanism is convenient and quick to operate, saving time and effort. Furthermore, the locking mechanism has high reliability, preventing the rotating arm and the plug and socket from easily coming loose, ensuring the quality of the circuit connection.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a locking mechanism for a vehicle high-voltage connector, comprising a socket 1 and a plug 5; the outer side of the plug 5 is rotatably connected to a rotating arm 3, and the rotating arm 3 is also provided with a latch 6; both sides of the socket 1 are provided with connecting pins 10, and after the rotating arm 3 is inserted into the connecting pin 10 through a provided slot 8, the connecting pin 10 slides in a guide groove 7 provided on the rotating arm 3; after the connecting pin 10 enters the limiting hole 9 provided on the guide groove 7, the latch 6 is adapted to and connected with a locking pin 4 provided on the outer wall of the plug 5 to lock the plug 5 onto the socket 1.

[0019] In summary, because the locking buckle 6 is directly provided on the rotating arm 3, when the plug 5 is connected to the socket 1, the locking buckle 6 will automatically lock onto the locking pin 4. Therefore, this locking mechanism is convenient and quick to operate, saving time and effort. Furthermore, this locking mechanism has high reliability, preventing the rotating arm and plug 5 from easily coming loose from the socket 1, ensuring the quality of the circuit connection. In particular, this locking method is simpler to operate and saves time.

[0020] Furthermore, since the plug 5 has a plug portion 2 inside, and the socket 1 also has a plug groove 12 for accommodating the plug portion 2, firstly, the plug portion 2 can be protected from the outside by using the plug groove 12; secondly, the connection area between the plug 5 and the socket 1 is larger, ensuring a stable and reliable connection between the plug 5 and the socket 1.

[0021] Furthermore, since the inner wall of the socket 1 is provided with a sliding groove 17, the plug 5 can slide along the guide rail 11 provided on the socket 1 through the sliding groove 17, so that the plug 5 can be smoothly inserted into the socket 1. Therefore, the plug 5 can be smoothly and stably connected to the socket 1, thereby ensuring that the electrodes in the plug 5 are smoothly connected to the electrodes in the socket 1, and completing the circuit conduction.

[0022] Based on the above solution, the bottom of the plug 5 is provided with a connecting part 18, and is connected to the connecting part 18 by a wire clamp 16, so as to fix the power cord inside the plug 5, thus enabling the power cord to be stably and reliably fixed on the plug 5.

[0023] Furthermore, a sealing gasket 14 is provided between the wire clamp 16 and the connecting part 18, and the sealing gasket 14 is fitted over the power cord. Therefore, the sealing gasket 14 can be used to prevent moisture from entering the interior of the plug 5 along the power cord.

[0024] Meanwhile, since both sides of the wire clamp 16 are provided with buckle grooves 15, the buckle grooves 15 are connected to the buckle pins 13 provided on the connecting part 18 to fix the sealing gasket 14 between the connecting part 18 and the wire clamp 16, thus making the installation and replacement of the sealing gasket 14 simple and convenient.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
